Owned by Franklin Street Properties and managed by Hines, 303 East Wacker is a 28-story, 838,000-square-foot office tower in downtown Chicago's East Loop area. Built in 1979 and designed by Fujikawa Johnson & Associates, the property is a handsome International Style tower, distinguished by a curtain wall of bronze-finished aluminum and reflective glass, and a two-story colonnaded arcade at ground level. Other building features include connections, via enclosed pedestrian walkways, to two hotels, five office towers, and a commuter railway station.


303 East Wacker earned the ENERGY STAR for superior energy performance as a result of both retrofits made during the renovation process and changes in energy management practices. For example, a new computerized building automation system was installed, enhancing control over energy-consuming equipment and enabling close monitoring of energy consumption, startup times, etc. HVAC upgrades were performed as well, including the installation of new Variable Air Volume (VAV) boxes, which allow the distributed volume of cooled return air to vary according to cooling demand. Heating equipment controlled by Silicon Controlled Rectifiers (SCRs) was installed as well. The SCRs operate like automatic dimmer switches, allowing heating equipment to operate according to actual demand.
